HENRY R. PLIMPTON, OF BOSTON, MASSACHUSETTS.

SOFA OR LOUNGE BED.

SPECIFICATION forming part of Letters Patent No. 247,683, datedSeptember 27, 1881.

Application filed April 7, 1880. (No model.)

To all whom it may concern Be it known that I, HENRY R. PLIMPTON, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented a new and useful Attachment for Sofaor Lounge Beds, &c., ofwhich the following is a specification.

My invention consists in the combination, with the back andbase of asofa or lounge bed, of re-entering toggles, flexible spring-plates, anda cord, operating together, substantially in the manner as will behereinafter more fully set forth in the specification, and pointed outin the claim.

In the drawings, Figure l is an end elevation, showing my device asapplied to a sofa or lounge bed. Fig. 2' is a rear elevation of thesame. Fig. 3 shows, in detail, a thin metallic plate, one end of whichis to be made fast to the back of the sofa or lounge, while one cornerof the other end is turned up, so that a cordor chain attached to itmay,when pulled, serve to turn it partly on edge, and thus pry away thecenter of the toggle, as shown in Fig. 4. Fig. 4 shows the central partof one of the toggles and a section of the metallic plate for throwingout the central joint of the toggle, and thus allowing the back to beturned down.

A and B represent the base and back of a sofa or lounge bed. To the baseI pivot a link, D, at G, and to the back I pivot a link, D, at O, thetwo links D and D being pivoted together at M, so as to form a togglewhen the back is up, as shown in Figs. 1 and 2. This pivot M passesbeyond the line which connects O and U, (see Fig. 1,) so that pressureon the back of the sofa or lounge will cause the center of the toggle topress against the back, or in the direction indicated by the arrow atT,Fig. 1. Thus the toggle device, which in the dotted lines of Fig. 1 is aleg and legthis plate, as shown in Figs. 2 and 3. Now, I

as this plate H K underlies the toggle, it is evident that it the cord Lis pulled it will twist the lower edge of the plate upward and outward,and thus force the toggle away from the back, as shown in Fig. 4. Thiswill throw the joint outside of the line of centers, and then the togglewill be free to bend outward, and thus allow the back of the sofa orlounge to be turned down.

I do not claim the toggles as such, nor in combination with the back ofa sofa or lounge.

My invention consists in so locating the center or pivot upon which thelinks of the toggleturn that when the back is up the toggles becomere-entering and self-supporting.

Having thus described my invent-ion, what I desire-to secure by LettersPatent is In a sofa or lounge bed, the combination of the back B, baseA, and the re-entering toggle D D with the flexible spring-plate H K andcord L, all operating together substantially as described, and for thepurpose set forth.

HENRY RICHARDSON PLIMPTON.
